CVE-2021-41170

31
FAUCET Score

CVE-2021-41170 affects neoan3-apps/template versions prior to 1.1.1, where the template engine allows direct passing and execution of closures. This critical vulnerability (CVSS 9.8) enables remote attackers to execute arbitrary code by manipulating input values that share names with existing methods or functions, leading to full compromise of confidentiality, integrity, and availability. While a multi-step attack is plausible, there is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
